Replacement S3 ABB Floppy Drives. 

These are brand new floppy drives modified so that they work with the S3 controller. ABB sell replacement drives for over twice this price!

They are a direct replacements for ABB part numbers 3HAB 2477-1 and 5736 067-2.

The S2/S3 series of robots ran from 1984 with the release of the IRB 2000 until the M93A controller which were manufactured in large numbers until late 1993 and even later. There are still many S3 robots still fitted in car plants all over the world, testament to their longevity. 

They use the 720k (1 meg unformatted) 3.5" floppy disks of the DS DD (double-sided double-density) type. They are also suitable for use with the S2 control system.


The original floppy drives fitted to ABB robots have an average MTBF of just 30,000 hours, the rest of the robot can last for well over 4 times this so the floppy drive is often the first thing to go.

Each drive is modified before being tested for function in an S3 cabinet- Format, read and write functions are tested before shipping.
